Ubuntu (Fresh Install) setup for Plutus Pioneer Program

Before we can get started in lecture 1, we first must get our development environment setup.

This guide will be using a fresh install of Ubuntu Linux. If you want to use Linux but only have a computer with Windows installed, you can run a virtual environment inside of Windows. A great step by step guide for how to get started can be found here:
How to install an Ubuntu VM in Windows

You can copy and paste any of the code in this guide directly into your terminal or IDE. If you are new to Linux and are unfamiliar with terminal shell commands, this cheat sheet gives a quick overview:

The haddock documentation is also a great source of information for all the public plutus libraries. This can be found here:
Documentation for all public Plutus Libraries

First, Open up the terminal to get started. We will first install the necessary dependencies first for a fresh copy of Linux.

We need to install Nix and get it configured properly to use IOG’s caches. In this guide we will be doing a single user install. Before we can install Nix, we need to make sure the version of Linux you are using has both curl and git installed. First run:

totinj@penguin:~$ sudo sh -c 'apt update && apt install curl'

Now that curl is installed, we can install git. Run:

totinj@penguin:~$ sudo apt-get install git

We can now install Nix single user install. Run:

totinj@penguin:~$ sh <(curl -L https://nixos.org/nix/install) --no-daemon

Output:
Installation finished!  To ensure that the necessary environment
variables are set, either log in again, or type
  . /home/totinj/.nix-profile/etc/profile.d/nix.sh

Now to finish, we need to set the environment with the following command notice from above. Very important here to replace totinj with your current Linux user!!

totinj@penguin:~$ . /home/totinj/.nix-profile/etc/profile.d/nix.sh

We now need to add Input Outputs caches to greatly speed up the building process. Without this step, you might be running nix-shell for days rather than minutes! This can be found here: IOG Binaries. Let’s create a new config file that has the associated IOG links. Run:

totinj@penguin:~$ mkdir ~/.config/nix
echo 'substituters = https://hydra.iohk.io https://iohk.cachix.org https://cache.nixos.org/' >> ~/.config/nix/nix.conf
echo 'trusted-public-keys = hydra.iohk.io:f/Ea+s+dFdN+3Y/G+FDgSq+a5NEWhJGzdjvKNGv0/EQ= iohk.cachix.org-1:DpRUyj7h7V830dp/i6Nti+NEO2/nhblbov/8MW7Rqoo= cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY=' >> ~/.config/nix/nix.conf
